Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294994490, here are decompositions:

  • 13 + 4294994477 = 4294994490
  • 41 + 4294994449 = 4294994490
  • 67 + 4294994423 = 4294994490
  • 103 + 4294994387 = 4294994490
  • 113 + 4294994377 = 4294994490
  • 151 + 4294994339 = 4294994490
  • 173 + 4294994317 = 4294994490
  • 179 + 4294994311 = 4294994490

Showing the first eight; more decompositions exist.
